This document discusses how to form superlative adjectives in English. Superlative adjectives express the extreme or highest degree of a quality to describe one thing among a group. They are formed by adding "-est" to short adjectives of one or two syllables, or using "most" before long adjectives of three or more syllables. Some common irregular superlative forms are also noted, such as "good" becoming "best" and "bad" becoming "worst". The document provides examples of superlative adjectives used in sentences to demonstrate their proper formation and usage.
